Flush Casement Windows

What are flush casement windows?

A casement window is one which is attached to the frame of the window by hinges and opens by swinging outwards. The hinges are usually on the side of the window but can be on the top when it is called an awning window, or on the bottom when it is called a hopper window. Unlike a sash window that slides up and down, a casement window sits permanently in place. Flush casement windows are those that fit flush into the window frame so that the frame and casement window itself all lie flat in one plane.

Casement windows are first seen in England in the 18th century, replacing earlier mullioned windows. Early casement windows had a number of panes of glass because of the difficulty in producing one large sheet of glass which could fill the whole window frame. Flush casement windows date to the 19th century and can be seen in Georgian, Victorian and Edwardian houses.

Recognising the parts of a window

If you are shopping for windows it is quite useful to know the different parts so that you are not baffled by window speak.

Around the outside of the whole window unit is the frame. The top of the frame is called the head, and the bottom is called the sill. At the sides of the frame are the jambs. Within the frame of a casement window there are traditionally two strong bars which were originally made of stone or wood. The vertical bar up the centre of the frame is the mullion, and the horizontal bar, which is usually towards the top quarter of the frame, is the transom. The transom is not always present in modern casement windows. Both of these elements used to help support and strengthen the frame. The sashes fit into the frame between mullions and the transom if it is present, and each sash comprises the glazing fixed in place by rails at the top and bottom and stiles at the sides.

Modern flush sash windows

A modern flush sash window is one in which the whole of the window including the mullion and sash lie flush with the frame so that when the sashes are closed the whole window presents a completely flush appearance. This is in contrast to the usual modern windows where the sashes overlap the frame.

Why would you want a flush sash window?

You may decide that you want flush sash windows simply because they will look particularly attractive on your house. They sit well in modern houses and can also give a minimalist feel if that is the style you are looking for.

However, the principal concept of producing the modern flush window is that it is in keeping with the appearance of traditional windows. This can be particularly advantageous if you have an older property such as a cottage or farmhouse or even a new build which is replicating this style of architecture. Another advantage is that they can help a building fit in with other, older, houses in areas where there are regulations about the changes permitted to windows.

Conservation Areas

If you live in a conservation area you will know that there are restrictions on the changes you can make to your house and that you have to contact your local planning authority in advance of any changes. In conservation areas the visual appearance of buildings is very important and every effort is made to preserve the original windows because they are an integral part of a building’s history. If you are in this situation and your windows have to be replaced for any reason, not just any window will do. Replacement of timber or aluminium windows with uPVC may be possible, and in these cases the uPVC windows invariably have to replicate the originals as near as possible.
